As noted earlier, some stakeholder concerns are well-served today by available architecture viewpoints, frameworks, or ADLs, while others aren't expressible with available, off-the-shelf approaches. Hence the theme of this special issue: exploring the space of architecting in the face of multiple stakeholder concerns and looking for solutions that help the architect in that space. The articles in this issue all demonstrate techniques for framing one or more stakeholder concerns. Some have confronted the topic within software architecture; others are included because they offer insights on concerns and viewpoints from other branches of software engineering.
